ANTICREEPER.

Specification of Letters Patent.

Application filed June 5, 1915. Serial No. 32,288.

To all whom it may concern Be it known that I, Pnimr lV. Moonn, a citizen of the lnited States, residing at Evanston, in the county of (look and State of Illinois, have invented new and useful Improvements in autieree 'iers, of which the following is a full, clear, concise, and exact; description, reference bein had to the accompanying drawing, forming a part of this specification.

'ly invention relates to improvements in means for preventing the longitudinal move ment or creeping of railroad rails, such devices beiing known as anti-creepers or anchors. Some of the features disclosed in the construction illustrated herein are covered by the claims of my Patent No. 1,140,345, issued May 18th, 1915. and of my Patent 1,17 ,653, issued March 14, 1916.

The general object of the present invention is to provide an improved one-piece anti-creeper. Other objects are to provide an anti-creeper which fits over both flanges of the rail base and is positively held to the rail by a pin which has a driving fit in an opening therein; to provide an improved anti-creeper of the type Which increases its grip on the rail base by a tilting action about a transverse horizontal axis; to provide an anti-cree mr which cannot be re moved from the rail without deforming it after it is once applied thereto; and to provide an effective anti-creeper of generally simplified construction.

The embodiment of the invention shown In the accompanying drawinp will serve to illustrate the various features involved. Numerous other embodiments of the iuw-ir tion may be devised.

Fig. 3 is a, side elevation thereof in iuclined position as it. is being applied to the rail base.

The rail anchor, in the term illustrated. consists of a single casting. preferably of malleable iron, part of which may therefore is a. top plan view of said anti be bent without breaking. for a purpose hereinafter explained. The device comprises a transverse element or cross-piece 1 adapted to be located beneath the rail base and having extensions or aws 2, 3 at oppofurther reinforced by webs 8, are located advance of the cross-piece he aws i2,

In asanchor, therefore. it is till it. in which position to one base flange of the rail with the rrlgr of the base adjacent to the vertical wall of the jaw 3. In this position, the other jaw 2 may be lifted until the cross-piece engages the bottom of the rail base. The entire structure is then shifted laterally until the rail base engages the vertical wall 14 of the jaw In this position, the opposite side of the rail base will clear or fall within the plane of the surfaces '16, 17. The rail anchor may now be swung to vertical or normal position, whereupon it will be positively engaged between the walls 14, 15 and 16, 17. The creeping thrust of the rail anchor will keep it in this position. However, to lock it in place, the arm 12 is bent downwardly as previously explained. The anchor thus deformed, cannot be removed from the rail. It cannot be moved laterally, as long as it is upright, and it cannot be tilted as the arm fits against the top of the rail base flange. To positively lock the anchor to the rail, a pin 19 is driven through the opening 13 and through an alined opening in the web of the rail. In drilling the hole, the arm 1.2 with its opening, may be used as a templet. The hole drilled is of small diameter being preferably the size ordinarily used in securing bond wires to the rails, and the pin is a drivin fit. The pin connection just de scribe insures the maintenance of the rail anchor in upright position. Even if the rail should retract and the flanges 6, 7 be frozen in the ballast, said rail anchor would not tilt readily to such position as to relax its hold, but would continue to engage the rail base, since any pivoting of the arm 12 about the pin 19 would cause the lower part of said arm to bind against the upper surface of the rail. base. If the ballast failed to yield, the anchor would thus resist creeping in a rearward direction also.

The invention is not limited to the particular embodiment described herein except where limitations appear in the appended claims. The device need not necessarily be made as a casting or with. the relative proportions and arrangement of parts. illustrated. I desire to cover, therefore, whatever suitable equivalent means may be devised which fall within the scope of said claims.

Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent of the United States is:

1. The combination with a railroad rail having an opening therein. of a one-piece anti-creeper fitting over both sides of the rail base and provided with a pin of such size as to have a driving fit in said opening to aid in securing said rail anchor in place.

2. An anti-creeper comprising integral means for engaging the opposite flanges of a rail base both above and below the same, means engaging a tie to transmit the creeping thrust thereto and to insure a tilting action whereby the rail base is firmly gripped by said anti-creeper, and an extension on oneof said rail engagingmeans having positive engagement with the rail to prevent tiltin in a direction which would relax the grip on the rail base.

3. A rail anchor comprising a yoke having an extension at each end thereof, the extension at one end fitting against the top, side and bottom of, the base flange, the extension at the other end also fitting against the top, side and bottom of the opposite base flange, but being cut away to provide a clearance suflicient to admit said base flange when said anti-creeper is tilted, and means for preventing tilting.

4. An anti-creeper comprising a body por-' tion which bears against the bottom of the rail, a air of gripping members integral with said body portion and extending up ward above the plane of said body portion, a depending member integral with said body portion, said depending member and gripping members being in substantially a vertical plane and in advance of said body portion and an extension on one of said gripping members cooperating with the rail to prevent movement of the anti-creeper in a direction to decrease its effectiveness.

5. An anti-creeper comprising a single member shaped to fit against the bottom of the rail and over the base flanges thereof and bear against the side of a' tie, the portion bearing against the bottom of the rail being to the rear, both of the portions fitting over the base flanges and the portion bearing against said tie, and an integral extension cooperating with said rail f r maintaining said anti-creeper in position.

(5. An anti-creeper comprising means which fit one side of the rail base, a downwardly extending flange beneath the side of the rail base which bears against the tie and an integral extension on the upper part of said means normally clearing the web of the rail and arranged to be bent adjacent. to said web after the anchor is positioned.

7. A rail anchor comprising a jaw fitting one side of a rail base, a tie-abutting flange beneath said jaw, an extension on said jaw having an opening therein, means passing through said opening for locking said anticreeper to the rail, and an integral extension having positive engagement with the opposite side of the rail base.

8. A rail anchor comprising a yoke consisting of a cross-piece having upwardly and inwardly turned extensions at opposite ends thereof arranged to grip the rail base, one of said extensions providing a clearance which permits the anti-creeper to be moved laterally with respect to the rail, said anti.- creeper having a portion arran ed to be bent to engage said rail thereby 0 structing said lateral movement and preventing the removal of the rail anchor from the rail.

9. An anti-creeper comprising a crossbar, an abutment at ear-h end thereof providing a pair of vertical walls between which the rail base iits, forward extensions on the ends of said ('i'osslnil' arranged to fit over the top of the rail base, and a downwardly extending flange at the forward end of each of said extensions.

10. An anti-creeper comprising a crossbar having a forward extension at each end thereof, each of said extensions having two vertical surfaces in the same plane arranged to fit against the side of the rail base, said surfaces on each side being slanted apart longitudinaliv, one of said forward exten sions being (UL away between the front and rear L-iari'aires su h n-idly to reveiw ilnrail base when the anrhor is tilted.

11. An anti-vreeper comprising a single memberhaving jaws which it the opposite side of the rail haw, the rail having an opening therein, an extension on one of said jaws having an opening therein and a pin passing through said latter opening and having a. driving fit in said first opening.

12. The combination with a railroad rail having an opening therein, of an antiereeper which grips both sides of the rail base, an extension on one side of said antiereeper having an opening therein alined with said first opening, and a locking pin passing through said alined openings.

13. The combination with a railroad rail, of a rail anchor having means for frictionally gripping both sides of the base thereof, and a pin fitting within an opening in said rail, said pin being independent of said anti-creeper but cooperating therewith to prevent Inovenwnt in such a. direction as to relax the hold thereof on the rail base.

In witness whereof, I have hereunto subsvribod my name this 2nd day of Jane, 1915.
